ARM

x86
On ARM processors, the stack is extended by 100 bytes.
On 960 processors, the stack is extended by 48 bytes.
On 486 processors, and on 386 processors used with an 80387 FPU,
the stack size is extended by 108 bytes.
This system call returns 0 on success, or an error code on failure.
Hex Mnemonic Description
0x08 ERR_OBJTFULL Node’s object table full.
0x0E ERR_NOTCB Exceeds node's maximum number of tasks. The
maximum number of tasks that can be
simultaneously active is defined by the
kc_ntask entry in the pSOS+ Configuration
Table.
0x0F ERR_NOSTK Insufficient space in Region 0 to create stack.
0x10 ERR_TINYSTK Stack size too small.
0x11 ERR_PRIOR Priority out of range.
1. Internally, the pSOS+ kernel treats a task name as a 32-bit integer. However,
when the application calls the kernel through the pSOS+ C language API, it
passes the task name as a four-byte character array.
2. A null name (for example, 32-bit binary 0) should not be used, because it may
be used elsewhere as an alias for the running task.
3. The pSOS+ kernel does not check for duplicate task names. If duplicate names
exist, a t_ident() call can return the tid of any task with the duplicate name.
